. with radio apparatus, the primary object besubjoined claims.

ing to provide a novel, artistic and useful article for the purpose had. in view.

Another Objectis to provide an attractive loud speaker which while pleasing to the eye, is characterized by a mellowness of tone heretofore unattainable.

.Other yobjects and attendant advantages will be hereafter explained or apparent from the. following description of one practical embodiment of myinvention, while the features of novelty are succinctly defined by the The accompanying drawing is a sectional elevation of a loud speaker for radiosets conventionally embodying this invention.

Referring more in detail to the drawing it will be seen that m novel loud speaker comrises a substantia base .1,- of glass or other insulate material having a central. cavity 2, in the underside thereof to accommodate the reproducing instrumentality 3. This reproducing instrumentality 3 -is conveniently cured in. place by a removable locking-closure. 4, and it is positioned therein co-axial with an orifice 5, affording communication with a fuiin'el shaped trumpet 6, seating at its lower end in -a ,counterbore 7 and provid- .ed adjacent its u per end lwith an external flange 8. The a oresaid base 1, it will be noted, is formed with an upstanding arcographically configured pedestal 9, having an outwardly curved lip 10, in which seats .a glass flare l11; and, lsaid flare, in turn, is afforded 'support at its lower end upon the external fiange 8 above referred to.

Fitted on the, fiare 11, is a frusto-conieal reticulate materia-l light screen 12affording .support for a fine ornamental silk orother light fabric shade 13, whereby the entire 'device is rendered artistic and attractive to the eye. Incidentally, itis to be particularly y observed that the lpedestal 9 andi flare 11, 'muy be 0f Ornate pattern, or otherwise con'- gured so as to provide a work of art with ahighly finished appearance.

Transversely across the top I support a removable cross bar 14, having pendent therefrom a cable 15,. and connected incandescent light 16, the latter being mainly functional as a diffuser for the sounds reof the screen 12 produced relative to the flare 11, and accord-` Ing to its size will bemo-re orless so effective.

`Altho'ugh'l have show n and described the trumpet 6 and fiare 11, as a two-piece structure, it will be perfectly obvious that they be clearly understood that the particular embodiment of my invention shown. and described is byway of example onl accordingly the right is hereby reserve to make such detail changes or variations as fairly fall within the scope of the subjoined claims.

Having described my invention what I -claim is;

1. A loud speaker comprising an insulate may be integrally formed; and I desire it to l material base adapted to hou'se Ia reproduc- Ing instrumentality, an intertted insulate material amplifying trumpet, and a Vscreen closure sup orted lon the trumpet -mo u th` with incan e'scent diffusing means pendent therefrom.

2. Aloud speakercomp'rising an insulate.

material base adapted to house a reproducing instrumentalit an,` arcographically configured pedestal Integral with said base,
